摘　　要：由于弹丸对混凝土靶体侵彻机理的未知性及混凝土力学性能的复杂性,因此可将弹丸侵彻混凝土过程看作是一个灰色过程。介绍了弹丸侵彻混凝土靶体侵彻深度的灰色模拟与预测模型GM(1,n)的建立方法和过程,通过GM(1,n)模型可以实现对弹丸侵彻混凝土介质侵彻深度的模拟与预测。通过算例计算表明,此模型对模拟和预测弹丸侵彻混凝土的侵彻深度可行,且计算量较小。As the unknown nature of mechanism of projectile penetrating the concrete target and the complexity of the mechanical properties of concrete, the projectile penetration concrete can be seen as a gray process. The establishment of methods and processes about the gray simulation and prediction model GM （1 ,n） were described. Through the gray model GM （1 ,n）,the simulation and prediction of penetration depth of projectile penetrating the concrete target can be achieved. The calculation results show that the model simulation and prediction of projectile penetration depth of concrete penetration is feasible,the result is valid,with a smaller amount of calculation.
